Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75978, here are decompositions:
- 11 + 75967 = 75978
- 37 + 75941 = 75978
- 41 + 75937 = 75978
- 47 + 75931 = 75978
- 109 + 75869 = 75978
- 157 + 75821 = 75978
- 181 + 75797 = 75978
- 191 + 75787 = 75978
Showing the first eight; more decompositions exist.
